Months of research was conducted on a root barrel washer to determine the best way to clean the equipment given that it was not designed to be easily taken apart and cleaned. Hard-to-reach places were identified through the tracking of vegetable matter and debris dispersed within the barrel washer during use. An acceptable level of cleanliness completed in a reasonable amount of time was identified. The equipment cleanliness was based on visual criteria only; further investigation of the microbial level is still required.

To the best of our efforts, areas of critical cleaning are identified in this checklist as well as all other sections necessary to clean.
